Volcanological models indicate this layer derived from a far larger eruption than any subsequently recorded event in the region. While a similarly large eruption would have a major impact on human populations in the region if it occurred today, it is important to note that such events are very rare in the Lesser Antilles, and there is no indication that another large eruption is imminent.
